Boeing is set to relaunch its Starliner crew capsule (with no humans on board) for a second attempt at docking with the International Space Station this Tuesday, Aug. 3. Boeing’s first try in late 2019 failed to reach the ISS but landed safely in the desert. 

The mission was originally scheduled to take off Friday, but it’s now aiming for Aug. 3 after an unexpected issue on Thursday with an ISS module firing its thrusters shortly after docking with the station. 

“The International Space Station team will use the time to continue working checkouts of the newly arrived Roscosmos Nauka multipurpose laboratory module (MLM) and to ensure the station will be ready for Starliner’s arrival,” said NASA in a statement.

Software defects and a communications link problem led to a premature end to the original Boeing test flight in 2019, though the CST-100 Starliner capsule landed safely back on Earth. The upcoming Orbital Flight Test-2 (OFT-2) mission is a chance for Boeing to thoroughly vet its hardware and software before a crew of three American astronauts flies on Starliner.

Both Boeing and SpaceX are part of NASA’s Commercial Crew Program, which is all about sending astronauts to the ISS from American soil. SpaceX has now delivered 10 astronauts to the ISS, and Boeing would like to catch up. First, it’ll need to show that its Starliner can safely reach the ISS and return to Earth.

NASA will livestream the launch, which is scheduled to occur at 1:20 p.m. PT (4:20 p.m. ET) on Tuesday Aug. 3. Coverage is expected to begin at 12:30 p.m. PT. 

Starliner will lift off on a United Launch Alliance Atlas V rocket. The capsule will be packed with around 400 pounds of crew supplies and cargo. If all goes well, it’ll dock with the space station about 24 hours later, on Wednesday Aug. 4. Docking will also be covered live by NASA’s NASA TV.

Starliner will spend between five and 10 days at the ISS before bringing research samples back to Earth. Boeing will aim to bring the spacecraft back for a gentle parachute landing in the desert of New Mexico.

“OFT-2 will provide valuable data that will help NASA certify Boeing’s crew transportation system to carry astronauts to and from the space station,” NASA said in a statement July 22 after successfully concluding a flight readiness review.

The mission is a key step for NASA’s plans to run regular crewed launches from the US, ending its reliance on Russian spacecraft. If all goes well, the first crewed mission, Boe-CFT, could launch in the next six months.
